Standby Power. In many cases, highly critical loads such as those identified
as mission critical or life support will be provided with standby emergency power
supplies (uninterruptable power supply, diesel generator, etc). In these cases, the
load under consideration can be downgraded from critical to interruptible or even non-
critical depending on the capability of the standby power supply.
Non-Critical Loads. Having identified all critical loads, those that remain
can be classified as non-critical and identified for first-step load shedding.
